I am particularly interested in anyone who has a Nehalem or Westmere era Xeon to try this one out, as well as anyone who can put significant load on it. Quite a few of the bugs we've found so far have only been visible when all the CPUs were kept busy at once. :) Thanks again! https://us-east.manta.joyent.com/arekinath/public/kpti/20180221T003551Z/platform-20180221T003551Z.tgz https://us-east.manta.joyent.com/arekinath/public/kpti/20180221T003551Z/platform-20180221T003551Z.iso https://us-east.manta.joyent.com/arekinath/public/kpti/20180221T003551Z/platform-20180221T003551Z.usb.bz2 Hi, with the USB image I am unable to use virtual console both on my Toshiba Satellite L855 laptop (Ivy Bridge) and as well as on Linux KVM (CPU is set as host-passthrough). The former KPTI image's virtual console works in both cases. However I am able to deploy SmartOS from the older KPTI image and then upgrade the system with the KPTI+PCID USB image and SSH to the system. When on Linux KVM I was able to run many tests from Phoronix Test Suite (from pkgsrc) - they all passed, could not break it (sorry :) ). I'll do the same on bare metal this week.
